The invention is used to improve and secure the assembly of a prosthetic dental cap and the support thereof, whereby said two parts are nested together and, optionally, glued. The invention is characterised in that the contact surface between the two parts to be assembled is significantly increased by means of one or more complementary relief designs which form at least one set of alternating elements, namely convex and concave portions of surface or ridges, on the contact surface of each of the parts to be assembled. In this way, when the two parts are nested together, no gap exists between the two parts, either empty or filled with a cement or other substance which is malleable for assembly and subsequent hardening, except a possible housing for a fine layer of glue. In a preferred embodiment of the invention, the contact surface between the two parts is a pyramid or a truncated pyramid with a star-shaped base, preferably comprising three or four arms. The invention also relates to parts which are fitted with the aforementioned relief designs in accordance with the invention, the method of fixing a cap to the support thereof using the inventive device, and the method of producing two parts consisting in using preforms and a computer-assisted design and production software program. |
